Good thing is that last batch I made did not seem to lead up the barrel at all. I did run a bullet through one of the cylinders and it took some pressure to get it through. It measured right at 0.451.

What would be a good sizing setup to begin with? The lee kit that mounts on top of a press?

Just ordered a 6 cavity mold, 358-158-RP for the 38 spc/357 mag.
